JOHN VEASY'COLLIER, OF NORTHAMPTON, ENGLAND.

MACHINE FOR MAKING HEEL S FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 593,349, dated November9, 1897. Application filed February 10,1897- Serial No. 622,830. (Nomodel.)

To all whom it may concern:

Be it known that 1, JOHN VEASY COLLIER,

a subject of Her Majesty the Queen of Great Britain and Ireland,residing at Northampton, in the county of Northampton, England, haveinvented certain new and useful Improvements in Machinery for MakingHeels for Boots or Shoes, of which the following is a specification.

This invention consists of the herein-described new or improvedmachinery for making heels for boots and shoes whereby there is aconsiderable saving of labor, thus reducing the cost of manufacture.Moreover, all the heels of a certain size can be built to a uniformheight, and the split lift can be built in the heel withthe othersections instead of being nailed onto the bottom after the heel isbuilt. 7 Y

7 I will describe my invention by referring to the accompanyingdrawings, in which Figure l is a front sectional elevation of a.

boot and shoe heel making machine constructed according to thisinvention. Fig. 2 is a sectional side elevation of the same on line X Xof Fig. 1. Fig. 3 is a sectional side elevation of the same on line Y Yof Fig. 1. Fig. 4 is a front elevation and plan of one of thepressure-blocks of the said machine. Fig. 5 is a front elevation andplan of one of the distance-blocks of the said machine. Fig. 6 shows apart of one of the said pressureblocks in front and side elevations andin plan. Fig. 7 is a plan of one of the heelmolds of the said machine,and Fig. 8 is a plan of one of the treadles of the said machine.

The same letters indicate the same parts throughout the drawings.

The said machine is constructed and operated as follows:

A is a machine-bed suitably supported, as by the legs a a Fixed to thebed A are four standards (marked B B B B provided with top bearings 19 bb b, in which revolves the three-throw crank-shaft 0, provided withfly-wheel c and driving-pulleys c 0 D D D are three plungers guided forvertical movement by the guides E E E fixed to the standards B B B B.These plungers are connected to the three-throw crankshaft 0 by theconnecting-rods F F F which at their top ends f are respectively jointedto the throws of the crank-shaft C and at Mounted so as to be capable ofsliding to and fro upon the bed A are three heel-molds G G G which areeach shaped internally at g to correspond with the shape of the sides ofthe required heel, so as to receive the various sections of which theheel is builtup. Each of these molds is guided by two planed strips a acast on the bed A and between which the mold will slide. p

Under the plungers D D D and above the molds G Gr G I provide the threepressureblocks H H H which are arranged for vertical movement by fittingon the two upright studs 1 I fixed to the bed A of the machine. Uponeach of the studs 1 I is a coiled spring J, which springs are strongenough to raise and maintain thepressure-blocks in their highestpositions against the nuts 2" on the top of the studs. Each of thepressure-blocks H H H has a removable projecting lower part h, adaptedto fit into the corresponding mold and press onto the heel therein. Theunder side of the projecting part h is made of a shape to correspondwith the seat of the boot upon which the heel when built is to be fixed.On the top of each of the pressure-blocks H H H there is a slidingdistance-block which is marked, respectively, K K K and are adapted toslide in guides k formed on the top of the pressure-blocks. For each ofthe distance-blocks K K K I provide means for pushing the distance-blockforward between the bottom of the corresponding plunger and the top ofthe pressure-block, so that the plunger will then act upon thedistance-block and force it and the corresponding pressureblock down.The means for operating the distance blocks consist of three treadles,(marked, respectively, L L L one for each distance-block, turning on afulcrum-shaft Z and continued beyond the same as an arm P, which bymeans of the connecting-rod Z is connected to the arm l of a bell-cranklever which turns on a fulcrum-pin Z and the other arm Z of which has apusher-piece 1' connected to it, so that when the treadle is pushed m,connecting it to a bracket m on the machine-frame, so as to draw thedistance-block back from underneath the plunger at the proper times, ashereinafter described.

- adhesive mixture.

Each of the three pressure-blocks H H H is provided with twodownwardly-projecting ratchets or catches h3 71 which at 71 are jointedto the pressure-block and near their lower ends each is made with anotch h. These catches pass through holes in the bed A and at theirlower ends are connected together by a coiled spring h so that when thepressureblock has been forced down to compress the boot-heel in themold, as hereinafter described, the notches it will engage underneaththe bed A and thus maintain the pressure-block in its lowest position.In order to release the catches 7L3 h to allow the springs J to raisethe pressure-blocks, I provide for each pair of catches two smallbell-crank levers 11. M, which by the rods n n are connected to theshorter. arm n of the corresponding treadle-lever N, N or N which turnon the fulcrum Z, so that when one of these treadlelevers N N N isdepressed the shorter arm n of the lever, together with the twoconnecting-rods n n jointed thereto, rises and turns the bell-cranklevers 11. n so as to force the catches h h farther apart, as shown onthe right-hand side of the machine, Fig. 1, so that the notches h willthen be free or the bed A and the pressure-block will rise.

The machine above in part described acts as follows: The various liftsor sections 0 of which the boot-heel is to be made are placed in one ofthe moldssay the first mold Geach lift being slightly covered with pasteor other The mold G will then be g in the position in which the mold Gis shown in Fig. 3. The mold G", with the heel-section 0 in it, is thenslid back along the machinebed A until it comes in contact with thescrewed adjustable stop 19 at the back of the machine, when the mold Gwill be immediately underthe pressure-block H, the exact position of themold being regulated by the stop 19. The workman now depresses thetreadle L, causing the pusher-piece Z to push the distance-block K underthe plunger D, so that this plunger in descending acts upon thedistance-block K and forces the pressureblock H down, so that its lowerprojecting part h acts upon the sections 0 in the mold G, and thepressure-block is held in this position by means of the catches 71, 71engaging under the bed-plate A, as shown in Fig. 1. The operator nowplaces the lifts of another heel in the second mold G and slides thismold under the plunger D and depresses the treadle L so as to insert thedistanceblock K under the plunger D which will then depress thepressure-block H and compress the sections in the mold G as shown inFig. 1. The operator then similarly forms another heel in the third moldG and de presses the treadle L so that the heel in the ence to the othertwo pressure-blocks. Immediately the plunger D has acted upon thedistance-block K and depressed the pressure-block H, as above described,so that the 7o mold G is compressed by the pressure-block H similarly,as above described, with refercatches 71 k catch underneath the bed Aand V the plunger has commenced to rise, the spring m draws back thedistance-block K, so that the moving plunger does not continue to actupon the pressure-block after it has been se- 7 cured in its lowestposition by the catches.

The first pressure-block H can now be released from the first mold G bythe operator depressing the treadle L, which, as above described, throwsoutwardly the catches h h free of the bed A and allows the pressureblockH to rise. The operator then draws mold G forward to the position sh ownby the mold G in Fig. 3 and the heel 0 is removed from the mold and thesections or lifts for another heel are placed therein and the mold G isslid back underneaththe pressure-block. H and the heel is compressed, asabove described, and so on, each heel being properly compressed whiletwo other heels are being built.

In order to facilitate the removal of thefinished heel from the mold, Imay provide for each mold a lever, such as Q, which turns on a fulcrum gat the front of the machine,and

has a piston g jointed to one of its arms q immediately underneath thecavity 9 in the mold, so that when the lever Q is depressed the pusherwill be raised and push the finished heel out of the mold.

Each of the treadles L L L is provided with a coiled wire spring Zconnected to the bed A of the machine for lifting the treadle after ithas been depressed, and the treadles N N N are similarly provided withsprings n for lifting them.

It will be seen that as the pressure on the lifts of the heel is appliedby power and is continuous the pressure is equal on each heel, andtherefore those heels which are nominally of the same height can all bebuilt to a uniformheight.

It will be evident that, if desired, the machine may be constructed withonly one or two or with more than three of the molds G G G andcorresponding pressure-blocks and plungers and accesssories withoutdeparting from the nature of my invention.

I wish it to be understood that I do not limit myself to the precisedetails herein described, and illustrated by my drawings, as it will beevident that they may be varied to some extent without departing fromthe na-- and shoes comprising a heel-mold adapted to slide to and fro onthe bed of the machine, the pressure-block guided for Vertical movementabove the said mold, catches for maintaining the pressure-block in itslowest position, springs or like means for raising the saidpressure-block, a plunger and means for moving the plunger up and downabove the pressure-block, and a distance-block with means for insertingthe same between the plunger and the pressure-block to cause the plungerto depress the pressure-block and compress the heel in the mold, allsubstanv tially as hereinbefore described.
